APPARATUS FOR DISPLAYING SIGNS.

SPECIFICATION forming part of Letters Patent No. 487,394, dated December6, 1892. Application filed July 22,1892. Serial No. 440,959. (No model.)

To all whom it may concern.-

Be it known that 1, DAVID L. IVIACDONALD, a citizen of the UnitedStates, residing in Fairview, county of Bergen, State of New Jersey,have invented new and useful Improvements in Apparatusfor DisplayingSigns or Advertisements, as will be hereinafter described.

This invention consists in securing disks or plates upon which signs oradvertisements are to be printed or painted to the ends of axle-- treesof vehicles in a fixed or stationary position, so that the inscriptionthereon may be easily read while the vehicle is in motion.

Figure 1 represents a side elevation of a wagon, to the ends of theaxletrees of which are secured disks or plates, upon which signs oradvertisements are to be printed or painted. Fig. 2 represents an edgeviewof a Wheel and fragment of an axletree with the advertisingdisk insection, to show one practical method of securing the disks or plates tothe ends of axletrees without interfering with the wheels thereon. Fig.3 represents a side elevation or face view of one of theadvertising-disks de tached from the axletree. Fig. 4 is a sectionalview of a paper disk provided with a metal rim for the purpose ofstiffening and maintaining the disk in shape. Fig. 5 represents acentral sectional view of a disk of fibrous material or metal, aspreferred, punched into the required form, to be placed over the hub ofa wheel and secured to the end of the axletree and provided with astiffening-rib of corresponding contonr, as will be described.

Similar letters of reference indicate corresponding parts throughout theseveral views.

In the accompanying drawings, A represents disks or plates mounted uponand secured to the ends of the axletrees B of a vehicle and firmlysecured thereto in a fixed position, so that the inscription thereon maybe maintained in an upright position to be read, or a painting properlydisplayed while the vehicle is in motion. As a convenient means ofsecuring these disks or plates to axletrees in common use, braces orsupports 0 are provided which receive and extend from the ends of theaxletrees in opposite directions over the hubs and behind the disks A,and to which supports or braces O the plates or disks are secured bybeing riveted thereto, as shown in Fig. 2, or in any other convenientmanner.

The central part of these support-s C are perforated to receive the endsof the axletrees and are retained in position thereon by means of thenuts E, which retain the wheels upon the axletrees. By this means ofsecuring advertising disks or plates upon the ends of axletrees saiddisks become detachable without disturbing the wheels thereon and may bequickly replaced by new ones, or the inscription thereon changed, as thecase may be, without injury to or disfiguring the wheels or axletrees,and while the vehile is in motion the inscription thereon easily read.In order to render these disks as light as possible and to materiallycheapen the costof manufacture, they maybe made of paper-board andstiffened so as to retain their shape and remain flat by means of metalrims F, which rims, for convenience of construction and to exclude themoisture from entering the edge of the board, are folded over and aroundthe edges of the disks, as represented in Fig. 4.

In Fig. 5 the disk A is punched or formed so as to receive and besecured to the end of an axletree and extends forward over the hubsulficient to permit the diskA to approach, but not to interfere with,the spokes of the wheel, the support 0 conforming to the contour of thedisk, as shown. It is not material that these disks A be secured to theends of the axletrees, so as to maintain them in a fixed positionthereon by means of the nuts E, as shown. Any other method of attachingthem may be substituted, if preferred; but utilizing thenuts with whichthe great majority of vehicles are provided is believed to bepreferable, because no new device or attachment is required, no extraexpense added, and may be readily fitted to almost any vehicle inpresent use.

Having thus fully described my invention, what I desire to secure byLetters Patent is 1. In combination with an axletree and wheel of avehicle, a detachable plate or disk adapted to be secured to the end ofsaid axletree in a fixed position, and upon which plate or disk signs oradvertisementsare to be displayed, substantially as herein set forth andshown.

2. In combination with an axletree and wheel of a vehicle, a detachableplate or disk of fibrous material adapted to be secured to the end ofsaid axletree in a fixed position, or disk signs or advertisements areto be dis- 10 and upon which plate or disk signs or adverplayed, saidplate or disk being punched or tisements are to be displayed, said plateor formed so as to extend over the hub of a Wheel, disk being providedwith a metal rim, subsubstantially as and for the purpose hereinstantially as and for the purpose set forth. set forth.
